The procedure of test for cracking due to environmental stresses on electric polyethylene insulation or sheath of cables
: Double Walled water bath : 15 x 15 x 18 (LBH in Inches)
Most materials when exposed to extreme cold over a period of time become hard and brittle. This test is designed to study the effect of cold temperatures on material under mechanical shock.
When the Cables / Electrical Equipments are subjected top extreme cold for a considerable duration of time, they may become hardened and stiff. Such hardness and stiffness cause cracking of the insulation or sh
Copper Purity Apparatus is designed to determine the purity of copper by electrolysis¬†method. The sample containing copper is dissolve in sulfuric¬†-& nitric acid mixture and a regulated current is passed
During the armoring process and subsequently during laying of the cable, the armor wires are subjected to torsion stress.¬† The test is conducted to evaluate the torsion resistance of the wire.
